Investigation of the pressure ratio and efficiency of a turbocharger centrifugal compressor with a vaned diffuser

This paper presents the performance of a conventional turbocharger centrifugal compressor with a vaneless diffuser with the primary aim to improve the pressure ratio and efficiency of the compression stage through the application of a low solidity vaned diffuser (LSVD). A cold-flow turbocharger test...
